hiv rash


Measles, a viral infection characterized by a rash and malaise, can become a complicated case that involves meningitis (inflammation of the tissues surrounding the brain) or multi-organ involvement. Death can and does occur, luckily, no one has died of it in the United States. Still, about a quarter of a million children die from it in under-served parts of the world where vaccine and/or treatment for measles is not available.

You may be asking yourself what the big deal is about 131 cases in a country of over 300 million. The real answer is that 131 is likely an underestimate of the true number reported to the health departments all over the country. Other cases may go unrecognized. People who are immune-compromised or sick with other conditions may develop measles and not know it. They may die from it and not know it. Other than the rash, there are few other ways to recognize it beyond lab tests that may take too long or be to costly to perform. Also, because measles is so rare, few physicians may recognize it on symptoms alone.

The other reason why this is a big deal is that measles is perfectly vaccine preventable. In the United States of America, in 2008, there should be no cases of measles. Living for your faith and beliefs is one thing; dying because of them is another. The worst offenders in the non-vaccination campaign are misinformed individuals who, with all the evidence to the contrary in peer-reviewed study after peer-reviewed study, still believe that vaccines cause diseases like autism or auto-immune conditions. The truth to this is that they might cause something, but the overwhelming evidence is that they don't. So slacking on measles means that they have been slacking in other vaccines, and that's a scary proposition.

HIV/AIDS in Pakistan: the context and magnitude of an emerging threat


STUDY OBJECTIVE: The objectives of this review were to: (1) assess the nature and comprehensiveness of information regarding HIV/AIDS in Pakistan; (2) to evaluate the extent of HIV/AIDS in Pakistan by epidemiological estimates; (3) to indicate the implications of the results for health policy in Pakistan and other regions at a similar stage in the epidemic. DESIGN: A structured review of published, unpublished, and government literature was undertaken to collate all available information and present a descriptive epidemiological profile of HIV/AIDS in the country. SETTING: Pakistan, a developing country in the South Asian region. National and regional information and analysis are presented in so far as the data allowed. Sample sizes varied from 1.35 million people screened at the national level to smaller studies of fewer than 100 screened. RESULTS: Data pertaining to HIV/AIDS in Pakistan showed the best national estimates of HIV prevalence as 64 per 100,000 (0.064%). Within patients with sexually transmitted diseases the seroprevalence was as high as 6100 per 100,000 (6.1%); in men with extramarital contacts, 5400 per 100,000 (5.4%) and was as low as zero in some studied populations as well. The average age of onset was reported as 30 years. It is estimated that if all incident cases of AIDS were to die, there would be at least 5000 deaths annually attributable to HIV/AIDS. CONCLUSION: Coupled with the extremely low awareness of HIV/AIDS in Pakistan, as well as growing number of cases, the AIDS epidemic is poised to take a hold in Pakistan. The presence of additional risk factors such as unscreened blood, and low condom use rates make the situation fertile for AIDS to become a major public health issue. Pakistan's health policy must be proactive in tackling this emerging health threat.
